Top 10 Foods Highest in Copper

Copper is an essential trace mineral required by the body for energy production, absorption of iron, bone and connective tissue production, immune system function, synthesis of some hormones and red blood cell formation. (1) It also forms part of one of the body’s key antioxidant enzymes superoxide dismutase (SOD).

A deficiency in copper can lead to weak bones, joint pain, vitamin b12 deficiency, iron deficiency, and anemia. (2)

Conversely, over-consumption of copper will lead to cramps, diarrhea, and vomiting in the short term, and can have neurological (mental) effects in the long term. (3)

High copper foods include seafood, mushrooms, tofu, sweet potatoes, sesame seeds, cashews, chickpeas, salmon, dark chocolate, and avocados. (4) The current daily value (DV) for copper is 0.9mg. (5)

Below is a list of high copper foods, for more, see the extended list of copper rich foods, high copper vegetables, and high copper fruits.

About Nutrient Targets

Setting targets can provide a guide to healthy eating.

Some of the most popular targets include:
  • Daily Value (%DV) - The %DV is a general guideline for everyone and accounts for absorption factors. It is the most common target in the U.S. and is the target on the nutrition labels of most products. It is set by the U.S. FDA.
  • Reference Dietary Intake (%RDI) - The Reference Dietary Intake (RDI) is a customized target accounting for age and gender. It is set by the U.S. Institute of Medicine. The RDI for amino acids is set by the U.N. World Health Organization. The daily value (%DV) builds on the reference dietary intake to create a number for everyone.
  • Adequate Intake (%AI) - Sets a target for Omega 3 and Omega 6 fats. The Adequate Intake is also set by the U.S. Institute of Medicine. It represents a number to ensure adequacy but lacks the same level of evidence as the Reference Dietary Intake. In short, the number is less accurate than the RDI.

    • See the Guide to Recommended Daily Intakes for more information.
